Best SVN setup to be able to help with the MediaWiki version

okay, I'm sure this conversation has occurred a bazillion times on the internet (google says so), but I'm too noob to filter it down to exactly what *I'm* trying to do, and I definitely am not clear on how to best set things up for *this* project.

I'm probably the last person who will ever be able to commit a meaningful patch, but I feel like a retard having used wget to get a copy back in February and now I use this version 100 times a day (easily), and I've been modifying files on my own, and I can't just merge the trunk into my "working copy". I especially feel like a idiot that I've submitted tickets that either I could have fixed or may have been already fixed in the repo, but I don't even know which revision I got with my wget back in February. I'm setting up subversion now. With the name change and 3.0 coming, how should I set up the two branches I need? I need the MediaWiki extension, and I need to pick a branch of the editor to put inside the extension.

Awesome to see to templates now sort alphabetically. If you want to take that particular feature live to Wikipedia though, it you'll have to find a better way to do that. Some sort of browsable hierarchy or a search widget (like the image search)

Next question: How do I put my custom fck_specialchar.html back in so that svn update doesn't smash it every time? Guess I'll find out, eh?

BTW, if it's possible, could I change my user name in the database from "existing" to "Niels"? Because on trac, I'm "Niels"
